“…that have an endemism rate of more than 40% [26]. In fact, the characteristic Mediterranean insular traits, such as different geographic situations (some islands are close, and others far away from the mainland), as well as their geographic and paleogeographic evolution (some islands have been isolated for a long time, while others have not), show particular features of plant diversity and association, so that as a result, within the Mediterranean Basin, islands and islets (and archipelagos) possess flora of exceptional diversity and represent the principal centers of plant diversity, particularly due to the restricted range of most of their flora [23][24][25][26][27]. Concurrently, it is also accepted that such plant diversity is seriously threatened due to numerous factors (physical, biological and anthropogenic); therefore, many plants on these islands need pressing measures, including, but not restricted to, protection.…”
